Song Yi has had a secret love for Lu Lin for seventeen years. The two have been in the same class from kindergarten to high school. Song Yi's love is hidden in the candies they share, the wrong question papers they hand out, and the umbrellas they hold on rainy days, but they never say it out loud. Chen Yu, the second male lead in high school, appeared, and Lu Lin got together with him and eventually got married. Song Yi completed this long farewell at the wedding. Seventeen years of companionship and heartbeat finally became a secret hidden in time.
Concept: The unspoken love in youth is also a precious footnote of growth.
